Jacobson and Sotiriou showed that rotating black holes could be spun up past the extremal limit by the capture of nonspinning test bodies, if one neglects radiative and self-force effects. This would represent a violation of the cosmic censorship conjecture in four-dimensional, asymptotically flat spacetimes. We show that for some of the trajectories giving rise to naked singularities, radiative effects can be neglected. However, for these orbits the conservative self-force is important, and seems to have the right sign to prevent the formation of naked singularities.
雅各布森和索蒂里欧表明，如果忽略辐射和自相互作用力的影响，旋转黑洞可以通过捕获非旋转测试体而被加速到超出极值限制。这将代表对四维渐近平坦时空中的宇宙审查猜想的违反。我们表明，对于导致裸奇点的某些轨迹，可以忽略辐射效应。然而，对于这些轨道，保守的自相互作用力是重要的，并且似乎具有正确的符号，可以防止裸奇点的形成。
